'Up All Night': Watch a clip from NBC's new comedy

As well as announcing some brand new drama series in its 2011-2012 schedule, NBC also unveiled some exciting comedies for us to look forward to! Among them is Up All Night, which has a dream cast including Christina Applegate, Will Arnett and Maya Rudolph (wow!) Christina plays Reagan, a new mom who's gone back to work with the support of her stay-at-home husband Chris (Arnett). The only problem is that Reagan's feeling a little jealous of her boss and best friend Ava (Rudolph), who's still free to enjoy parties and late nights! Watch a clip from Up All Night below:
